Polymerase cofactor VP35 - Q05127 (VP35_EBOZM)

Protein Feature View of PDB entries mapped to a UniProtKB sequence

Acsts as a polymerase cofactor in the RNA polymerase transcription and replication complex. Prevents establishment of cellular antiviral state by blocking virus-induced phosphorylation and activation of interferon regulatory factor 3 (IRF3), a transcription factor critical for the induction of interferons alpha and beta. This blockage is produced through the interaction with and inhibition of host IKBKE and TBK1, producing a strong inhibition of the phosphorylation and activation of IRF3. Also inhibits the antiviral effect mediated by the host interferon-induced, double-stranded RNA-activated protein kinase EIF2AK2/PKR. (data source: UniProt )

Subunit structure

Homooligomer. Homomultimerizes via the coiled coil domain. Found in a trimeric complex in which VP35 bridges L and the nucleoprotein (By similarity). May interact with VP40. Interacts with host IKBKE and TBK1; the interactions lead to inhibition of cellular antiviral response by blocking necessary interactions of IKBKE and TBK1 with their substrate IRF3.
